Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh environments and extended service life.
- Exceptional holding power and minimal backlash ensured by the Class 3A thread fit and fine UNF thread spacing.
- High durability and deformation resistance provided by the Rockwell B80 hardness rating.
- Secure, flush mounting in confined spaces enabled by the headless design and compact 3/32" hex drive.
- Positive, non-slip grip on shafts and components delivered by the aggressive cup point tip.
- Reliable performance and interchangeability guaranteed by compliance with the ASME B18.3 specification.
- Safe for use in regulated industries as it is RoHS 3 and REACH compliant.
Professional Applications & Engineering Value
This 10-32 UNF set screw is engineered to solve critical challenges in precision assembly and motion control systems. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it a reliable choice for applications exposed to moisture, chemicals, or outdoor elements. The headless design and cup point work in tandem to create a secure, permanent lock on pulleys, gears, and collars without protruding, preventing interference in compact machinery. The fine thread spacing and Class 3A thread fit offer a tighter tolerance than standard fits, which is crucial for applications requiring high vibrational resistance and precise axial positioning. This combination of features makes it an indispensable component for demanding industrial applications in automotive, aerospace, and manufacturing equipment where failure is not an option.
Specification Summary & Compliance
This set screw features a 10-32 UNF thread with a Class 3A thread fit for high precision. It is manufactured from 18-8 Stainless Steel to a hardness of Rockwell B80 and conforms to the ASME B18.3 standard. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
